“…Scirpus validus is an aquatic plant widely used in sewage treatment [16] that presents good removal rates of nutrient salt [17], heavy metals [18] and organic compounds [19]. For example, S. validus is effective at removing ammonia nitrogen and nitrate and at effectively promoting the transformation of nitrogen and significantly reduce the residence time of inorganic nitrogen in wetlands [20].…”

Eutrophication is a phenomenon of excess nutrition that results from the natural or artificial enrichment of inorganic nutrients such that the system cannot regulate the circulation of nutrients [1]. Among 118 lakes in China, the proportion of mesotrophic lakes was 21.4% and that of eutrophication was 78.6% in 2016 [2]. It is clear that China faces serious water eutrophication, which will affect the ecological landscape and the safety of livestock drinking water [3]. Many factors lead to eutrophication and predominantly involve the addition of nitrogen and phosphorus [4]. In particular, nitrogen is an important cause of eutrophication [5], especially ammonium nitrogen and nitrate nitrogen contents. Large amounts of nitrate-enriched water pose a serious threat to human life and production. The World Health Organization [6] found that drinking high-nitrate water can endanger human health and safety [7]. As a result,

“…However, microbial investigations of floating beds have rarely been documented (Zhang et al . ). Microorganisms in aquatic environments have been proved to have major roles in the nutrition of the cultured animals, water quality and disease control (Moriarty ), and could provide sensitive, meaningful and quantifiable indications of ecological change (Paerl et al .…”

“…Many researchers have conducted investigations focusing on the nutrient removal effects or biomass accumulations of plants (Zhu et al 2011;Zheng et al 2013;Zhang et al 2014c;Rao et al 2016). However, microbial investigations of floating beds have rarely been documented (Zhang et al 2014a). Microorganisms in aquatic environments have been proved to have major roles in the nutrition of the cultured animals, water quality and disease control (Moriarty 1997), and could provide sensitive, meaningful and quantifiable indications of ecological change (Paerl et al 2003).…”

With the increasing demand for environment friendly aquaculture, artificial floating beds have been now widely applied. However, there are few data available on the effect on microbiota in ponds. This study assessed the rhizobacteria community of artificial floating beds with three different kinds of aquatic plants [water spinach (Ipomoea aquatic), water hyacinth (Eichhornia crassipes) and alligator weed (Alternanthera philoxeroides)]. We used Polymerase Chain Reaction‐Denaturing Gradient Gel Electrophoresis to assess whether artificial floating beds would result in changes in microbiota of pond water and gut of grass carp (Ctenopharyngodon idella). The results showed that there existed no significant differences in rhizobacterial composition, and artificial floating beds would not greatly affect the microbiota of pond water. The dominant microbiota in the guts of grass carp changed from Aeromonas jandaei to Paenibacillus sp. Our results indicated that artificial floating beds may serve as a candidate of modulating fish gut microbiota.

“…Recently, constructed wetlands, which are less expensive and produce more environmentally safe end products, have become a more common wastewater treatment technique [2] (Yan and Xu 2014). Selection of wetland plants is important to wetland system design, and plant types can include aquatic plants and floating and submerged plants, each of which has unique cleaning effects [3] . A study on the effects of nine kinds of plants on treatment of livestock and poultry breeding wastewater found water treated through a constructed wetland containing plant beds to be better than water passed through a constructed wetlands not containing plant bed.…”

A wetland containing canna, calamus, wild water chestnut and Hydrilla verticillata was constructed to measure wastewater purification efficiency and effects of livestock wastewater on the physiology of the wetland plants. The results showed that the highest removal efficiencies of the same three contaminants among all four wastewater concentration treatments were 96.42%, 91.09%, 79.07% respectively. Tolerance of livestock wastewater was greatest for canna, followed by calamus, and then wild water chestnut, whereas Hydrilla verticillata was least tolerant of the livestock wastewater treatments.
